7. We’ve moved past analog!
ˈanlˌôɡ/
adjective 1.
relating to or using signals or information represented by a continuously variable physical quantity such as spatial position or voltage.

8. We are in the
age and we’ve moved past analog in almost every way…….

9. Except for Dimming!!!!

10. Why are we still controlling solid state lighting with an analog signal?

11. It’s like designing a Printed Circuit Board

12. On a Drafting Table!!

14. It’s time to move dimming to Digital!

15. It’s time to move dimming to Digital!
And Digital in Lighting is

16. It’s time to move dimming to Digital!
And Digital in Lighting is DALI

17. It’s time to move dimming to Digital!
And Digital in Lighting is DALI

18. What is DALI? DALI = Digital Addressable Lighting Interface
It is a communication standard designed specifically for lighting.

19. What is DALI?
DALI defines how each component in a lighting control system communicates.
True 2-Way Communication!

20. DALI is also an “Open” standard. Why is that important?
What is DALI?
DALI is also an “Open” standard. Why is that important?

21. What is DALI?
As an open standard any manufacturer can create devices that communicate using DALI.

22. What is DALI?
For example a DALI driver from one manufacturer will work with control stations, sensors, etc. from any other manufacturer using DALI.

23. What is DALI? Levels the playing field
End user creates the exact system for their needs
OEM’s have to become more innovative with their products
More focus on design and customer service

24. What is 0-10v? A varied input from 0 to 10v One way communication
The scale for 0-10v values are set by the individual manufactures.

25. What is 0-10v? A varied input from 0 to 10v One way communication
The scale for 0-10v values are set by the individual manufactures.

26. 0-10v dimming curve(s)

27. DALI Curve

28. So why isn’t it used more in the United States?

29. So why isn’t it used more in the United States?
The Drivers are more expensive than 0-10v Drivers

30. So why isn’t it used more in the United States?
The Drivers are more expensive than 0-10v Drivers

35. $4 to $6 premium on DALI Drivers
Harvard Technology
$4 to $6 premium on DALI Drivers

36. So why isn’t it used more in the United States?
Installers don’t have experience with DALI

37. So why isn’t it used more in the United States?
Installers don’t have experience with DALI

38. Lutron Eco System

39. Lutron Eco System
Is DALI!!

40. Lutron Eco System
Or rather based on DALI. It has been modified to be proprietary, but still retains all of the functionality of DALI.

41. The real reason’s its not used more

42. The real reason’s its not used more
Early DALI Systems were a nightmare to commission!

44. The real reason’s its not used more
Early DALI Systems were a nightmare to commission!
Lighting Control manufacturers didn’t see the need for DALI!!!

Exact color temperature no matter how long the wire runs.
0-10v
Color temperature changes with long wiring runs

90. Human Centric Lighting (HCL) DALI vs. 0-10v
Exact color temperature no matter how long the wire runs.
Exact color temperature on fixtures from different manufacturers
0-10v
Color temperature changes with long wiring runs
The same command sent to fixtures from different manufactures will produce different color temperatures.

91. Human Centric Lighting (HCL) DALI vs. 0-10v
Exact color temperature no matter how long the wire runs.
Exact color temperature on fixtures from different manufacturers
Less Components and cheaper to install
0-10v
